Abstract
A wheel arrangement for a rail vehicle, such as a light rail vehicle, can include a wheel unit and an axle unit. The axle unit can be connected to a running gear structure of the rail vehicle. The axle unit can rotatably support the wheel unit. The axle unit can have a wheel bearing unit that forms a bearing for the wheel unit and defines a wheel axis of rotation of the wheel unit during operation of the rail vehicle. The axle unit can also have a wheel support unit and a primary suspension unit. The primary suspension unit can be located kinematically in series between the wheel support unit and the wheel bearing unit such that the wheel support unit supports the wheel bearing unit via the primary suspension unit in a manner resilient in at least two mutually transverse translational degrees of freedom.
